Rating Methodology

CarbonGrade ratings are derived from a structured and consistently applied evaluation model

INSTITUTIONAL FRAMEWORK

CarbonGrade ratings are issued under a defined internal rating methodology designed to evaluate corporate carbon performance and reporting robustness at organizational level.

The framework establishes:

  • Scoring architecture
  • Evaluation indicators
  • Weighting structure
  • Classification thresholds (A–E)
  • Interpretation rules.

Ratings reflect both carbon intensity positioning and data integrity quality within the defined reporting scope.

SCOPE OF EVALUATION

CarbonGrade ratings:

  • Are issued at organizational level
  • Are valid for a defined reporting year
  • Are based exclusively on documented disclosures submitted by the rated organization
  • Reflect carbon performance relative to sector positioning
  • Incorporate methodological robustness and transparency criteria

CarbonGrade does not provide certification. Ratings represent structured classification outcomes under the CarbonGrade framework.

EVALUATION PROCESS

The assessment process follows a defined and consistent sequence:

  1. Submission of documented carbon inventory and supporting disclosures
  2. Documentation review and completeness verification
  3. Indicator-based scoring under the defined architecture
  4. Application of classification thresholds
  5. Issuance of rating outcome (A–E)

All rating decisions are derived exclusively from submitted documentation and internal scoring criteria.

CLASSIFICATION MODEL

CarbonGrade applies a structured five-level classification structure:

A — Leading
High carbon performance and strong data robustness.

B — Strong
Above-average performance with minor methodological limitations.

C — Baseline
Performance aligned with sector norms.

D — Weak
Below-average performance or structural limitations.

E — Insufficient
Material data integrity gaps or incomplete reporting.

Final classification results from structured internal scoring.

METHODOLOGICAL INTEGRITY

The CarbonGrade methodology is structured, version-controlled, consistently applied and publicly referenced.
Methodological updates, when applicable, are documented and applied prospectively.
